Powers:Ripjak possesses superhuman physical abilities and wears an exoskeleton for support. His abilities without the exoskeleton are uncertain. His true form was originally one of the semi-amorphous, gelatinous bodies of the Martian Masters. His armor grants him superhuman strength (Class 25-50) and durability. Given the source of his powers, he would also likely possess superhuman speed, agility, endurance, etc.
In addition, he can extend six tentacles which can be used as extra-limbs, but also contain certain forms of weaponry, such as energy blasters. His armor can absorb and analyze various forms of energy
Many of the Martian Masters possess some degree of telepathic power. It is not certain if Ripjak has any of these abilities. He has not demonstrated any "spider-sense" sort of power.
Similarly, Ripjak's lifespan is unknown, but he is at least a few hundred years old.

Bio:A Martian scientist, Ripjak was initially tasked with engineering the "Final Pillage," the last culling of Earth's resources hundreds of years after the initial invasion. With this task a success, he returned home a hero and was given a chair in the High Overlord's cabinet. When, soon after, a mysterious and incurable plague began killing his fellow Martians, he was tasked with finding a way to halt its spread. While initially believed to have been an Earth-borne bacteria similar to the kind that had halted the Martian invasion of the 19th century, Ripjak believed differently. With a climbing death toll, the High Overlord himself contracted the disease, becoming desperate for any cure. Theorizing earth might hold the cure, Ripjak sealed himself in the war museum, home to all of the war trophies brought back from Earth, including a sarcophagus holding the remains of Spider-Man, the last of Earth's defenders. Removing the preserved heart of the hero, Ripjak began experimenting with Spider-Man's radioactive blood and though the High Overlord perished before the work was completed, Ripjak managed a cure, injecting himself with the formula. While he became immune to the virus, he also underwent a long and painful mutation process. When the process had completed, he found himself the last Martian. Instructing his lab-droids, he had them build a custom exoskeleton, becoming the first super-powered Martian: Ripjak.
